35 Claims. 1

This invention relates to elapsed time and earnings computing and recording machines and particularly to such mechanisms wherein the elapsed time and earnings amounts are computed and digitally recorded so as to be immediately available upon completion of the recording operation.

As a basis for various accounting and control operations in business management, one of the fundamental records is the job time card or time record, which according to past practice has been assigned to each worker, or individual job, or order, so that the worker may record start and finish time thereon in respect to each job, order, or work period. Desirably such time cards should of course bear such identifying data as may be necessary or convenient for accounting or control purposes, such as man number, job or order number, date, the mans pay rate, department, operation number and machine number, and the like, but according to past practice the preparation of these cards prior to issuance to the worker has in most instances included but a part of such information.

Even Where such time cards have embodied all of the various items of data hereinabove listed, such cards after recording of the start and finish time thereon, have usually constituted nothing more than intermediate or partially completed records which merely afforded a basis upon which further calculating and recording operations were to be based. Thus, after the start time and finish time were recorded on the card at the usual departmental time clock, such card was stored in a suitable collecting means so that at a later time, such as the end of the work period, all of the collected time cards might be taken to the time clerk or auditing department for the performance of the required computing and recording operations, and for recording of related information or data that may have been omitted in the original preparation of the cards. Thus, assuming that at least the man number and the mans rate have been originally placed on the card, the auditing department must, from the recorded start and finish times, determine and record the elapsed time and the earnings, and usually in addition, a burden amount must be calculated and recorded in accordance with a burden rate which may vary with the department, job number or other circumstances. Such calculations and the recording and verification or checking thereof require considerable time so that the completed time cards are notavailable for accounting or control uses for a considerable time after the time recording operations have been completed. Where it is the practice to use punched card equipment for payroll and accounting purposes, further time is required for the perforation and verification of the punched cards. Apart from the objectionable cost factors involved in such prior procedure, the delay in the availability of the completed time cards minimizes the value of such records to the management, and it is therefore an important object to enable such delay to be eliminated; and objects related to the foregoing are to enable completely computed time cards to be produced as an incident to the recording of the finish time thereon; to extend the field of data recorded on such cards so as to enable greater and more extended and valuable uses thereof; to enable punched time records containing all pertinent reference and computed data to be produced when the finish time is recorded so as to thereby eliminate the usual cost and delay incident to the subsequent computing and key punching of such records.

Efforts have of course been made heretobefore to simplify the problem of producing the final elapsed time and computed earnings records, but in such prior efforts the problem has been but partially met, and as a result such prior efforts have not received any appreciable degree of commercial acceptance. One such prior approach to this relatively old and well recognized problem has been through graphic representation of elapsed time on an elongated record strip so that elapsed time is represented by the length of a line or by the space between two marks representative, by their position, of start and finish time. This of course serves merely to change the character of the first one of the secondary operations from one of computation to one of measurement, and does not in fact eliminate any delay or save any appreciable time insofar as final completion of the time and earnings record is concerned. Similar means have been applied to the earnings amount, in some cases, and further improvement of this approach has been the association of readable scales with the marks upon the record strip or sheet.

In other efforts to accomplish the obviously desirable simplification of the preparation of time and earnings records, it has been proposed to furnish an individual time clock to each workman, and to include computing means in each such clock operable to compute earnings at the proper rate for the man to whom the clock was allocated. Usually such individual time clocks were re-set to zero at the start of each job,

3 and in some instances were controlled from a master clock. Such duplication of equipment obviously was objectionable from the standpoint of original cost, space requirements, maintenance and for other reasons.

In other instances efforts have been made to employ in one machine, a plurality of time controlled computing and recording units each controlled at a different pay rate, or to employ a single clock and recording unit but with a plurality of internal and cooperating computing means for computing elapsed time and for extending earnings at any one of several different rates, but in such instances, the number of regular and overtime rates in use in a department has limited the application 01 this approach. Likewise, these efforts have greatly limited the amount of detail available, usually confined to computed elapsed time, computed earnings, or both, for the period, in addition to a man or machine number indication.

The manner of comparing the start time and the finish time to compute the elapsed time, and means to compute the period earnings, have taken inany Iorms, such as manual insertion of the start time by the worker, at the time of the Out registration, or or the insertion, incident to the Out registration, of such start time, or of cumulative earnings, or of an arbitrary, timecontrolled earnings position, by means of holes punched in the record card at the time of the prior In registration.

In instances'where efforts have been made to compute earnings at multiple rates, recourse has been had to a plurality of time-controlled computing units within the machine, and the storage of the start time or other factor indicating a time or money status at the beginning of the period, has been either internal in the machine, or associated with the card or record sheet upon which the final recording is to be made. The limitations of these approaches have been conclusively :proven by the very limited use which has been made of such means commercially, though the problem is one which has challenged the ingenuity of inventors for decades.

Documents for recording data have taken the form of printed records, of notched or punched card records, and of combinations thereof, but not of two separate, identical records, one punched and one printed. It may be stated generally that methods and means afforded to date have been unsuccessful for one or more of several reasons, such as, excessive original cost, mechanical or capacity limitations, incomplete or inadequate data record, maintenance problems, or because the disclosed mechanisms were impractical of production or in operation.

In view of the foregoing deficiencies of prior efforts to simplify the production of elapsed time and earnings records, it is a further and more specific object of the present invention to enable a single machine to produce such records at any one of a large number of regular or overtime pay rates and with respect to a relatively large number of workmen. A related object is to enable this to be accomplished in such a way that the earnings amount and any related money amounts invariably will be computed at the proper rate.

Gther important objects are to enable start time and. other data related to a job and to the man performing the job to be stored in a supplemental device in respect to each such job, thereby to avoid storage of such data in the machine per 4 se, and by this mode of procedure to extend the range of usefulness of the machine.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show a preferred embodiment and the principles thereof and what I now consider to be the best mode in which I have contemplated applying those principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.
